Owner reports

Selected complaints filed with NHTSA by 2011 Mercedes-Benz C300 owners, lightly cleaned up (personal details are redacted by NHTSA).

I was in a collision and the airbags did not deploy. There was a recall on airbags for the Mercedes C300 within the year my vehicle was made, however, the recall did not include my VIN. Also, the sunroof drain is faulty, which was also recalled on other Mercedes C300s within the same production year, again not my VIN, but upon inspection by a certified dealership, it appears to be the same issue as other recalled vehicles.

The sam box (electrical system fuze panel) located under the hood is in a spot where if the lid isn't on correctly water will drain from the windshield right into the sam box and cause the vehicles electrical system to deploy the steering wheel airbag. That's at least what happened to me. It was raining out that day and I guess I went over a bump that caused the lid of the sam to get out of place. I drove home and the car seat for a few hours. I went out upon unlocking the door as soon as I pulled the handle to open the driver side door the steering wheel airbag blew and the vehicle is now in srs mode. The dealership had told me that it's a design flaw but wants me to pay for the diagnostic. No lights were on and I did not file a police report.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel system failure is a highly critical safety concern, and my life is at risk. It causes malfunctions with the vehicle, for example, the OBD-based emissions test has flagged a lot of (codes P219A, P0300, P0304, P0410, P0305, P0303, P0171, P0301) 5 of the cylinder misfire codes with the check engine light on, as well affecting other parts in the vehicle function properly, acceleration issues, car stalling as though it's going to shut off. This is a serious matter and Mercedes-Benz is failing to prioritize customer safety, over cost especially when known faults in the vehicle can lead to potentially life-threatening incidents such as fuel leaks and fire hazards. Yes, the vehicle is available for further inspection upon request immediately each day my life is at risk. …

Desiccated Air Bag Inflator Rupture

NHTSA investigation EA21002 · opened Sep 17, 2021 · open

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
